Reborn as a mosquito? A system where you become stronger by sucking blood?

Chu Sheng was a little silent about this opening.

I've turned into a mosquito, how strong can I become?

But anyway, I have to give it a try...

Chu Sheng randomly flew into a room, and unexpectedly there was a gorgeous girl inside.

Good! Just suck her!

…

Gu Yuexi, an emperor-level beastmaster and empress of the human race!

In her previous life, she didn’t start the beast taming journey until she was sixty years old, and the first beast she contracted was only of low-level bloodline, which led to an unstable foundation and its death in the heavenly calamity.

When she was reborn at the age of eighteen, she must become a beastmaster as soon as possible!

She spent all her money to buy a demon beast with high-level bloodline and prepared the blood contract ceremony!

Just as she was about to sign a blood pact with the monster, a mosquito flew onto her leg and sucked a mouthful of her blood!

“…”

"My name is Gu Yuexi. I seem to be useless in this life..."
